Finding the most optimal parameters for a moving average strategy and backtesting

I'm looking for a couple of people with extensive experience back testing Expert advisors.

I have had a EA coded which has various variables and I want to find various profitable presets to run.

Id like to find a profitable data set for XAUUSD, XTIUSD, NAS100, EURUSD, GBPUSD etc across a variety of time frames.

This is a ongoing role.

Ideally you can run multiple instances of mt4 at any one point of time to conduct your back testing.

Experience is a must.

$100 Paid per profitable preset.

When testing start with 100 K account. Assume a max of 1 % risk and

Daily Drawdown can not exceed 4%

Max account DD can not exceed 10% over a month.

Most be sustained over the last 12 months.

The EA is custom made for me.

Ideally i want to work with someone long term.
